Abstract

First, a measurement unit (105) measures the reception SIR of a control channel signal allotted to the presently selected sector in accordance with information indicating the selected sector held by a selected sector holding unit (106). Then, a comparison unit (107) compares the reception SIR with a predetermined threshold of the reception SIR which is set in a storage unit (108). Only when the reception SIR is lower than the predetermined threshold, the measurement unit (105) measures the reception SIRs of a plurality of control channel signals, and the selection unit (109) selects the control channel signal which exhibits a maximum reception SIR among the measured reception SIRs.
